servo: drv/loglevel: Change EC-3PO's loglevel too.

This commit amends the loglevel driver to change the loglevel of the
EC-3PO console interpreters as well.  Since the console interpreters
are in different processes, simply changing the loglevel of the root
logger is insufficient.

BUG=None
BRANCH=None
TEST=start servod; issue dut-control loglevel:debug; verify that both
servod and ec3po debug log messages are emitted.  Issue dut-control
loglevel:info; verify that no debug messages are emitted.

CQ-DEPEND=CL:325134
